NOTES: (1) For Two’s Complement Input Coding invert the MSB with an external logic inverter. (2) Digital inputs are TTL and +5V CMOS compatible over the

specification temperature range. (3) Open DATA input lines will be pulled above +5.5V. See discussion under LOGIC INPUT COMPATIBILITY section. (4) FSR means

Full Scale Range. For example, for

±10V output, FSR = 20V. (5) Adjustable to zero with external trim potentiometer. (6) Specified with 500Ω connected between

VREF OUT and VREF IN. (7) Error at input code 800HEX. DAC2813 specified with 100Ω connected betweenVREF OUT and VREF IN; and with 500Ω connected between VREF

OUT and BPO. (8) Maximum represents the 3σ limit. Not 100% tested for this parameter. (9) For the worst-case code change: 7FFHEX to 800HEX and 800HEX to 7FFHEX.

(10) Crosstalk is defined as the change in any output as a result of any other output being driven from –10V to +10V at rated output current. (11) The maximum voltage

at which ACOM and DCOM may be separated without affecting accuracy specifications.
